1. 1. Question Types of Volcanoes There are three major types of volcanoes that form differently. The chart below describes how and where they form, where they are located, and gives examples of each type. Formation, Location and Examples of Different Volcano Types Shield Composite/ Stratovolcanoes Cinder Cone Formation/ Location Massive fluid lava flows and slowly builds up a gently sloping volcanic shape. Location Primarily located along tectonic spreading centers or at "hot spots." Examples Kilauea, Mauna Loa (Hawaii) Built from both explosive eruptions and quieter eruptions. Layers of tephra (ash, cinders, and other material blown into the air) alternate with layers of lava to create steep-sided often symmetrical cones. Stratovolcanoes are located primarily along tectonic subduction zones, where two plates slowly collide. Mount Fuji (Japan), Mount St. Helens (Washington) Made primarily from explosive eruptions of lava. Blown into the air, the erupting lava breaks apart into the small fragments known as cinders. The fallen cinders accumulate into a cone around the volcano's central vent (the "hole in the ground" from which the lava emerged). Not associated with any particular tectonic activity. Some are found near current tectonic boundaries, and others are near old boundaries. Sunset Crater (Arizona), Capulin Mountain (New Mexico) What term is used for a volcano formed by explosive eruptions, where lava breaks into cinders, accumulating into a cone around the central vent, and is not tied to specific tectonic activity? a. Shield b. Composite c. Cinder Cone Correct answer d. Stratovolcano Incorrect C: Cinder cones are volcanic formations primarily created through explosive eruptions, where the ejected lava shatters into small cinders, forming a cone around the central vent.

Question Prevalence of Both Diagnosed and Undiagnosed Diabetes Among the US population overall, crude estimates for 2021 were: • 38.4 million people of all ages—or 11.6% of the US population—had diabetes. • 38.1 million adults aged 18 years or older—or 14.7% of all US adults—had diabetes. • 8.7 million adults aged 18 years or older who met laboratory criteria for diabetes were not aware of or did not report having diabetes. This number represents 3.4% of all US adults (Table 1a) and 22.8% of all US adults with diabetes. • The percentage of adults with diabetes increased with age, reaching 29.2% among those aged 65 years or older (Table 1a).
